Re: [ADSM-L] Bad volume rule of thumb

Some time read/writes error can be due to bad drives. I have seen with
LTO2 drives. Once i replace them all look good.
Good luck

Hi Nicholas

You don't say what your tape technology is.  I used to admin a site that
had LTO1 and LTO3 drives.  With the LTO1s I would run move data on any
tape in error, and if that worked record the volser of the tape.  After
three errors, or if the move data didn't work I would discard the tape.
For the LTO3s I discovered that any error tended to be permanent.

I currently work a lot with LTO2s and they fail similarly to LTO1s, but
more of them fail hard on the first error.

Regards

Steve.
